TFS1 thresholds correlate with age independent of audiometric hearing loss

Evidence

Moore et al. ( 2012 ) used the TFS1 test with centre frequencies of 850 and 2000 Hz to test 35 subjects with audiometric thresholds ≤ 20 dB HL from 0.25 to 6 kHz and ages from 22 to 61 years. There were significant correlations between age and the thresholds in the TFS1 test (r = 0.69 and 0.57 for the centre frequencies of 850 and 2000 Hz, respectively). However, TFS1 scores at 850 Hz were correlated with absolute thresholds at 850 Hz (r = 0.67), even though audiometric thresholds were within the normal range, making it hard to rule out an effect of hearing loss. — Dijk, Pim van, Physiology, Psychoacoustics and…, 797

Categorization

• QUESTION: The correlation with normal-range absolute thresholds confounds age and subclinical hearing loss — worth chasing how studies disentangle the two.
